RIVET-CATCH ER.

SPECIFICATION forming part of Letters Patent No. 639,503, dated December19, 189 9. Application filed September 5, 1899. Serial No. 729,457. (Nomodel.)

To all whom it may concern:

Be it known that I, WILLIAM J. BEIGHEY, of Oonnoquinessing township, inthe county of Butlerand State of Pennsylvania, have invented a new anduseful Improvement in Rivet-Catchers, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, in which to Figure 1 is asectional side elevation showing one form of my improved rivet-catcherin position. Fig. 2 is a cross-section on the line II II of Fig. 1, andFig. 3 is a central vertical section showing a modified form.

My invention relates to the rivet-catchers employed in connection withdeep wells to prevent broken rivets from passing into the pumping-barreland injuring the parts; and its object is to make the construction moreeconomical and durable, as well as to improve the operation of suchdevices.

In the drawings, referring to the form of Fig. 1, 2 represents a bulgedcollar or coupling havinginner screw-threads in its end portions, whichare of reduced diameter. The tubing 3 is screwed into the upper end ofthe collar, and the working barrel 4: is screwed upwardly into its lowerend, the barrel being threaded a sufficient distance, so that its endportion 5 will project up some distance within the coupling and form apocket of annular form in the lower part of the coupling. The upper endof the working barrel forms a seat, upon which rests a hollow perforated3 5 double cone 6, both conical portions being provided withperforations to allow free and uninterrupted flow of liquid. The ends ofthe cone are, provided with holes, through which the valve-rod 7extends, the rod reciprocating through the double cone, which is seatedon the top of the working barrel.

In using the device the tubing, with the collar 2 and the workingbarrel, is lowered to the proper position, and the valve-rod,

with the double cone resting thereon, is lowered, with the rods, throughthe casing until the cone rests upon the upper end of the workingbarrel, the valves being lowered into the barrel. With the parts in thisposition the pump works in the ordinary manner, the rod reciprocatingthrough the double cone without lifting it from the seat. Theperforations in both end portions of the cone allow a free flow ofliquid, while any rivets or foreign matter falling through the tubingare deflected by the upper cone and fall into the annular pocket in thelower part of the sleeve.

The pocket within the sleeve may be formed in many other ways than thatshown without departing from my invention. Thus the bulged sleeve mayhave an inner sleeve of the desired length secured within its lower endsby screwing, riveting, or shrinking it in place or by casting itintegrally with the collar.

If the collar is not adapted to fit and. screw upon the Working barrel,I may use the supplemental sleeve or nipple 8, which is provided withexternal screw-threads, its lower end being screwed into the collar 9 atthe top of the working barrel, the upper end portion of the nippleprojecting up into the bulged collar to form the annular pocket, asbefore. The action in this form will be the same as that in Fig. 1.

The advantages of my invention result from the durability, cheapness,and simplicity of the device, which does not interfere with theregular-pumping operations. There is nothing to become disarranged,injured, or worn out, While any rivets or foreign matter are effectuallytrapped, so as to not harm the working parts.

Many changes maybe made in the form and arrangement of the parts withoutdeparting from my invention. I

I claim--- 7 1. An enlarged collar or coupling arranged to be securedabove the Working barrel, an annular pocket formed in its lower part,and an inner perforated double cone or deflector arranged to rest uponthe pocket portion within the collar; substantially as described.

2. In a rivet-catcher, an enlarged collar or coupling arranged to besecured above the working barrel, and having a hollow bushing projectingupwardly in its lower portion to form a pocket, and a double conedeflector arrangedto rest upon the bushing and having and arranged todeflect foreign matter into a, hole for the valve-rod; substantially asdethe pocket; substantially as described.
